Question

A grating has 810 lines per centimetre, and a flat screen is perpendicular to the ray that makes the central peak of the diffraction pattern. The screen is 2.20 m from the grating. If light of two wavelengths, 630 nm and 670 nm, passes through the grating, what is the separation on the screen between the fourth-order maxima for the two wavelengths?

Answer #1

A grating has a line density of 1090 cm−1,
and a screen perpendicular to the ray that makes the central peak
of the diffraction pattern is 3.5 m from the grating. If
light of two wavelengths, 620 nm and 650 nm,
passes through the grating, what is the separation on the (flat)
screen between the fourth-order maxima for the two wavelengths?

Suppose that you have a reflection diffraction grating with
n= 105 lines per millimeter. Light from a sodium lamp
passes through the grating and is diffracted onto a distant
screen.
Two visible lines in the sodium spectrum have wavelengths 498
nmand 569 nm. What is the angular separation ?? of the
first maxima of these spectral lines generated by this diffraction
grating?
How wide does this grating need to be to allow you to resolve
the two lines 589.00 and...

Light from a Hydrogen lamp is focused through a diffraction
grating with 770 lines/cm and the diffraction pattern is shown on a
screen that is 5.30 m away. You notice in the pattern that there
are two distinct purple dots that are 16.46 cm and 17.70 cm from
the central maximum, corresponding to the first-order maxima for
two different wavelengths of light emitted by the lamp. What is the
difference between the two wavelengths (in nm)
corresponding to these purple...

You have a diffraction grating with 3000 lines/cm. You also have
a light source that emits light at 2 different wavelengths, 428 nm
and 707 nm, at the same time. The screen for your experiment is 1.5
meters from the diffraction grating.
A. What is the line spacing for the grating?
B. What is the difference in the angle of the 2nd bright fringe
for each wavelength for this grating?
C. Which wavelength is closer to the center of the...

Light of wavelength 600 nm shines on a diffraction grating that

middle of the screen. Assume that the screen is 3 m from the
grating.
How many maxima appear on the screen?

A diffraction grating with 355 lines/mm is 1.2 m in front of a
screen. What is the wavelength of light whose first-order maxima
will be 16.4 cm from the central maximum on the screen?

A
student shines a monochratic light through a diffraction grating
with 4,000 lines per cm. the distance between the grating and the
screen is 1.2 m. The student measures the distance between the
first order fringe and central maxima at 0.2cm. What is the
frequency of the monochromatic light? Show work.

Green light of wavelength 500 nm passes through a diffraction
grating having 10−610−6 m between lines.
How far away from the central bright spot is the next bright
spot on a screen 2 m away (in meters)?
Suppose the light passing through the diffraction grating is
composed of many different wavelengths. Rank the following colors
according to the spacing between the bright spots of that color
from least to greatest, so the least would have the smallest
spacing between maxima....

24.73 . LIght is incident on a diffraction grating with 8600
lines/cm , and the pattern is viewed on a screen 2.5 m from the
grating. The incident light beam consists of two wavelengths,
4.5×10?7 m and 6.9×10?7 m .
Part A Calculate the linear distance between the first-order
bright fringes of these two wavelengths on the screen.

A
diffraction grating with spacing d = 2000 nm produces an
interference pattern on a screen at a distance of 32 cm. If the
first and second maxima produced are located at y = 3 cm, and 5 cm
respectively, what is the wavelength of the light? Is this light
visible? What does that say about the screen in this apparatus? If
the frequency of the light used in question 1 above is decreased,
will the positions of the maxima...
